The error was: (error "rx ‘**’ range error") Backtrace: " backtrace-to-string(nil) org-element-at-point() org-in-src-block-p() run-hook-with-args-until-success(org-in-src-block-p) electric-quote-post-self-insert-function() self-insert-command(1 34) funcall-interactively(self-insert-command 1 34) call-interactively(self-insert-command nil nil) command-execute(self-insert-command) " Best, Alejandro > On Feb 22, 2022, at 9:06 PM, Ihor Radchenko <yanta...@gmail.com> wrote: > > Alejandro Pérez Carballo <apcarba...@gmail.com> writes: > >> I was simply entering an entry to my main bib file.
